AUTOMATIC REGISTER FOR GRAINS, SEEDS, AND OTHER SUBSTANCES.

SPECIFICATION forming part of Letters Patent No. 293,129, dated February5, 1884. Application filed November 3, 1883. (X model.)

To aZZ whom, it may concern.-

Be it known that I, JOHN \VHERRY, J r., of Putnam, in the county ofPutnam and State of Illinois, have invented a new and useful Improvementin Automatic Registers for Grains, Seeds, and other Substances, of whichthe following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional front elevation of my improvement. Fig. 2 is asectional side elevation of the same, taken through the broken line 00cc, Fig. 1. Fig. 3 is a rear elevation of the lower part of the same,partly in section and part being broken away. Fig. 4: is afrontelevation of a part of the same, showing the registering mechanism.

The object of this invention is to facilitate the measuring of grains,seeds, and other substances as they come from a thrashing-ma chine, abin, or other receptacle, and also to promote accuracy in suchmeasurements.

The invention consists in a grain-resister constructed with atwo-compartment case provided with an adjustable guideplalte connectedby levers and rods with hinged bottoms having elastic bars engaging withweighted scalebeams, whereby a given weight upon one bottom will shiftthe guide-plate and raise the other bottom into position. Thescalebea-ms are provided with catches and spreaders, so

that the said elastic bars will engage with and release the saidscale-beams automatically. The adjustable guide-plate is provided with acrank operating a push-pawl, which engages with a ratchet register-wheelprovided with a wire to engage with a succeeding ratchet register-wheel,the said register-wheels being provided wit-h holding-pawls, so that thesaid register-wheels will be revolved through uniform spaces by themovements of the said guideplate, as will be hereinafter fullydescribed.

A-represents the case of the register, the body of which is maderectangular in form. The upper part of the sides of the case A areinclined inward and then outward, forming a flaring or hopper-shapedmouth, the inward inclination of the sides being such that the throatthereby formed will be about half the diameter of the body of the saidcase. The body of the case A is divided into two equal compartments by avertical partition, B, the upper end of which is at a little lower levelthan the lower ends of the inward inclination of the sides of the saidcases.

To the front and rear sides of the case A, at the upperend of thepartition B, is pivoted the lower edge of a plate, C, so that the saidplate can be turned to either side, to serve as a chute to guide thesubstance into one or the other of the compartments of the case A: The

upper edge of the plate C swings in beneath the inwardly-pro ectingangle of the sides of the case A, as shown in Fig. 1, so that the grainor other substance, when entering the said case, cannot get between theupper edge of the plate C and the side of the case A and impede themovements of said plate. The plate C,when swung to either side, restsupon ledges or flanges D, attached to the inner surface of the case A,as shown in Fig. 1, to support the said plate against the pressure ofthe entering substance.

To each side of the plate C is attached an angular rod, E, to the angleor outer end of which is pivoted the upper end of arod, F, the lower endof which is hinged to the outer part of the bottom, floor, or platformG, attached to the rigid inner parts of the pair of bars H. The bars Hare pivoted to a bar, I, or other support placed in a slot in the rearwall of the case A, and secured to a frame, J, surrounding the lowerpart of the said case. The side bars of the frame J are extended to therearward, and are connected by a crossbar, J, to which and to the bar orplate J, attached to the lower side of the rear part of the frame J, aresecured the lower ends of the bars K. The upper part of each bar K isbent inward, and is attached to the rear side of the case A, each bentbar K being in such a position that the rearwardly-proiecting ends of apair of the bars H, will move along its opposite sides as the said barsare vibrated by the upward and downward movements of the hinged bottomsG. The projecting parts of the bars H are elastic, and between the barsof each pair is placed a scale-l cam, L, the inner end of which ispivoted to the pivot of the said bars, H. The outer end of each beam L,

Q teams or a tenonformed upon the said end, moves up and down in a slotin the lower part of the bar K.

To the upper side of each beam L, a little in the rear of the lower partof the bar K, is attached a catch, M, the ends of which project a littlebeyond the sides of the beam L, and are beveled upon their upper sides,so that the elastic bars H in their downward .movements will pass thesaid catch, but will carry the said beam L with them in their upwardmovements.

Upon the opposite sides of the lower part of each bar' K are formedprojections N, beveled upon their upper and lower sides, so that thesaid projections will spread or separate the elastic bars H, to causethem, as they move upward, to release the catch M and allow thescale-beam L to drop back to its place, and to cause the said bars intheir downward move ment to pass the said catch., As the bars H movedown past the catch M, they spring in beneath its projecting ends, readyto raise the scale-beam L in their next upward movement.

0 isarod, the ends of which are bent upward at right angles, and areattached to the lower side of the forward part of the scalebeam L.

From the rod 0 is suspended a weight, 1 which is secured in place uponthe said rod 0 by a set-screw, Q, which passes through the eye or blockthat connects the said weight with the said rod. Vith this constructionthe weight I? can be adjusted nearer to or farther from the pivoted endof the scale-beam L, according as alighteror heavier grain or substanceis to be measured, so that the bottom G will trip as each half-bushel orother fixed quantity of the substance is received in one of itscompartments. As the fixed quantity of the substance is received in acompartment of the machine, the bottom G of the said compartment dropsand the substance is discharged. As the bottom G drops, the elastic barsmove upward and release the scale-beam L, so that all the substance willescape, and the said bottom will remain in its downward position untilraised by the downward movement of the bottom of the other compartment.The downward movement of the bottom of each compartment shifts the plate0 so as to direct the substance into the other compartment, theoperation of the machine being automatic. The elasticity of the bars His regulated by a bolt, R, passing through them at a little distancefrom their pivots.

S is a plate, hinged at itsupper edge to the rear wall of the case A insuch a position that its lower edge will rest upon the bottom G, toprevent any of the substance being measured from getting between therear edge of the said bottom G and the rear wall of the case A andobstructing the movements of the said bottom.

To a projecting pivot of the guide-plate O is attached or upon it isformed a short crank, T, to which is pivoted a pawl, U. The pawl Uengages the teeth of a ratchet-wheel, V,

pivoted to the case A, or to a support at tached to the said ease, thecrank T being made of such a length as to cause the pawl U to revolvethe ratchet-wheel Vthrough the space of one tooth.

To the ratchet-wheel V is attached a wire keeper or pin, XV, which, ateach revolution of the said wheel V, engages with a tooth of a secondratchet-wheel, X, and turns the said wheel X through the space of onetooth. In the same manner a third and fourth ratchetwheel can be used,as may be required.

To the wall of the case A are pivoted pawls Y Z, to engage with theteeth of the ratchetwheels V X and hold the said ratchet-wheelsfrombeing turned back by the friction of the pawl U and wire XV. Thepawls U Y Z are kept in place by keepers a, attached to the case A. Theratchet-wheels V X are designed to be provided with index-fingers anddials, to show the amount of the substance measured.

\Vith the arrangement herein shown the pawl U will be drawn back by thedescent of one of the bottoms G and pushed forward to turn theratchet-wheel V by the descent of the other bottom, so that when theweights 1? are adjusted to allow the bottoms G to trip as eachhalf-bushel of the substance is received the registration will be madein bushels.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A grain register constructed substantiall y asherein shown and described, and consisting of a two-compartment caseprovided with an adjustable guide-plate, and hinged bottoms havingelastic bars engaging with scale-beams, as set forth.

2. I11 automatic grain-registers, the combination, with the flanges D D,arranged on the inner and opposite sides of the case A directly underits throat, of the vertical partit'ion B, swinging plate 0, pivoted tothe up per end of said partition, rods E F, and pivoted platforms G,substantially as shown and described.

3. In a grain-register, the combination, with the case A and the hingedbottom G, of the pairs of elastic bars H, the weighted scalebeams L,having catches M, and the spreaders N, substantially as herein shown anddescribed, whereby the said hinged bottoms will be released when a givenweight of the substance has been received upon them, as set forth. 7

i. In a grain-register, the combination, with the scale-beams L and theelastic bars H, of the catches lllf and the spreaders N, substantiallyas herein shown and described, whereby the said elastic bars are made toengage with and release the scale-beams automatically, as set forth.
